4. Regularly check the ear cushions for wear and clean them
occasionally as necessary with a damp cloth or distinct ear
cushion surface with non-alcohol PPE wipes (Do not use harsh
detergents or any solvents which may damage the ear cushion
over time). Check the ear cushions for wear. If the cushions
become hard, damaged or otherwise deteriorate, they should be
replaced promptly (Contact Sena or your authorized dealer for
exact replacement parts).
Warning
Hats, balaclavas, glasses or other items worn on the head may
potentially prevent proper sealing and reduce the level of hearing
protection signicantly which can possibly cause hearing damage.
Although hearing protectors can be recommended for protection
against the harmful effects of impulsive noise, the Noise Reduction
Rating (NRR) is based on the attenuation of continuous noise and may
not be an accurate indicator of the protection attainable against
impulsive noise such as gunre.
NRR example
1. The environmental noise level as measured at the ear is 92 dBA.
2. The NRR is (value on label) decibels (dB).
3. The level of noise entering the ear is approximately equal to [92
dB(A) - NRR dB(A)].
Caution
For noise environments dominated by frequencies below 500 Hz “the
C weighted environmental noise level should be used.”
WEEE (Waste Electrical and Electronic Equipment)
The crossed-out wheel bin symbol on the product,
literature, or packaging reminds you that all electrical
and electronic products, batteries, and accumulators
must be taken to separate collection at the end of their
working life. This requirement applies to the European
Union and other locations where separate collection
systems are available. To prevent possible harm to the environment or
human health from uncontrolled waste disposal, please do not dispose
of these products as unsorted municipal waste, but hand it in at an
ofcial collection point for recycling.
